Many people around the world worship the e=mc[^]2 formula and worship Einstein for that formula which says that the energy produced by an amount of gold is the same energy produced by the same amount of lead: Al last, the lead become gold, the old dream of the Alchemists!. With 1 gram of sand one can produce the energy that produce 1 gram of Uranium!. Isn't that marvelous?

In his letter to President Roosevelt - August 1939, Einstein clearly shows that the above formula is just a fraud, he didn't encouraged Roosevelt to use water, sand, garbage or paper, but just the very specific element URANIUM:

You are correct. Einstein wrote to Roosevelt about what would happen if you split a uranium atom. Roosevelt setup the Manhattan project to build a bomb based on Einstein's notes.
And look what happened! The fact that Hiroshima and Nagasaki were reduced to smoldering radioactive ruins in a matter of seconds is undeniable proof that Einstein was right. If he was wrong then the bombs never would have worked and the US would have had to physically invade Japan.

On everything else you're just so god damned uniformed and stupid that it hurts.

You moron. If we had so much gold then it would no longer be precious. Just look at aluminium. It was more precious than gold in the days of Napoleon. To him our use of it as wrapping material would be "madness".

Einstein provided the equation as a way to liberate energy from radioactive compounds as a source of power.

Which we do use today... For that purpose. Not to transmute stuff because that is very very expensive to use all that energy for forming trinkets of gold.

I suppose, in theory, 1g of silicon dioxide (let's keep it simple) could produce as much energy as 1g or uranium... if you had a way of making it turn completely from matter into energy.

Incidentally, it is possible (through different means to utilising Einstein's equation, which would have little if any impact) to transmute other chemicals into gold, but the process is so difficult and costly you could only make a loss. I do recall that a sample of gold was produced from another element. That element, though, was platinum.
